bug in composer.json - shaark does not provide ext-imagick

[cklm]

Hello, the composer.json says, that this project provides an implementation of the php-extension ImageMagick (imagick). That leads to false data for other people using imagick:

$ composer install
Loading composer repositories with package information
Updating dependencies                                 
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires PHP extension ext-imagick * but it is missing from your system. Install or enable PHP's imagick extension.

      Alternatively you can require one of these packages that provide the extension (or parts of it):
      - marceauka/shaark Your place to archive your links, stories, passwords and archive your content.
      - metadeck/blog Blog
      - metadeck/nova-blog Nova Blog


To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php84/php.ini
You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-imagick` to temporarily ignore these required extensions.

As can be seen, composer suggests this package to people, who are missing the php-extension - but this project does clearly not provide an alternative to the extension. Maybe this is a typo and "ext-imagick" should go to the required packages?

Same here!
That's completely wrong.
This should be removed to prevent confusing others.

It may be that this repository requires the Imagick extension, in which case the line "ext-imagick": "*" should be put into the requires block, but I'm not sure if that is intended so my PR simply removes the "provides" section.
